Credits
Your plan's credits are worth exactly what you pay.
One rate, $1 per 1,000 credits, and $20 a month buys 20,000 of them. Building docs, keeping them current, and every other AI action draw from the same pool — no per-feature pricing to work out. Free accounts are read-only: browsing and reading, no AI.
- Allowance first, credits second — you're never charged twice for the same work
- Credits never expire
- Buy any amount from 1,000 to 100,000 · bonus credits on larger top-ups
- One rate for everyone — the top-up price doesn't depend on your plan
